===Age===
Age does not have an influence on your skills except if you are particularly young or old. Most character starts as a fully developed young adult with no modifier for its age. Each race has a lifespan unit that represents how fast this race gets old. When under the age of maturity, you received a cumulative -1 age penalty for each 2 lifespan units. When over your lifespan, you received a cumulative -1 age penalty per lifespan unit.
''For example, a human is mature at 15 years old. If your character is 12 years old, you suffer an age penalty of -2. The average lifespan of a human is 75 years. An 80 years old character would have a -5 age penalty.''
